Abstract
Based on the construction scheme of the south bank of Guoyang County shiplock,a two-dimensional flow mathematical model and a physical model are established to analyze and validate the navigable flow conditions in the lower approach channel.The results show that:① there are sharp bends in the lower reaches of the project,the flow deflects sharply,there is oblique flow in the entrance area,and the lateral velocity of the flow is large,which is not conducive to navigation;② the navigation conditions of the lower approach channel can be effectively improved by adopting the optimal engineering measures of adjusting the route,cutting the shoal and dredging the channel.The transverse velocity,longitudinal velocity and backflow velocity of the recommended scheme meet the requirements of the code,and effectively improve the backflow and crossflow phenomena.It can provide reference and basis for the design of later shiplock scheme,and provide reference for other similar shiplock to improve navigation flow condition.关键词
